Spencer Bennett Dr. Field Structural Geology 312 November 13, 2014 The Lithology and Structure of the Grand Teton Range, Wyoming Abstract Wyoming’s Grand Teton range has a vast variety of rock units, along with an assortment of ages and names. Along with the variety of lithology that the Teton Range has to offer it also has a unique normal fault the has down dropped Jackson Hole and up lifted the Teton range. The geological history is also quite exceptional knowing that the structure of the Grand Teton range began over 2.5 billion years ago. Introduction The Grand Teton area consists of some of the oldest and youngest rocks, and mountain ranges, in America. They are found in the Middle rocky Mountain physiographic province. The core …show more content…

The Teton range has an elevation of 4 197.096 meters with eight peaks over 3 657.6 meters in elevation. Lithology Geological structures in Grand Teton National Park are found within the Middle Rocky Mountain physiographic province, and result from tectonic events associated with the Laramide orogeny. The Tetons are still affected by these events today. The Laramide orogeny is primarily responsible for bringing Precambrian metamorphic and plutonic rocks, those composing the core of the Tetons, to the surface. The Teton Range consists of a core of igneous and metamorphic Precambrian rocks overlain in most of the range by westward dipping sedimentary Paleozoic rocks. The Grand Teton Range consists of rocks ranging from the Precambrian, Paleozoic, Mesozoic, and Cenozoic time periods. The erosion-resistant Precambrian rocks comprise the highest peaks of the Teton Range and are part of the Wyoming Craton. The oldest units (>2680 Ma), observed in the north, south, and the eastern part of the central Tetons, are Archean layered gneisses, including biotite gneiss, plagioclase gneiss, amphibole gneiss, and some amphibolite (Reed and …show more content…

The Tetons have been glaciated at least three times, with the oldest event being the most widespread event. These great ice masses shaped and sharpened the Tetons. Beginning 2 million years ago glaciers began to erode and sculpt the Teton Landscape. Large masses of ice flowed from the topographic high of the Yellowstone Plateau down across the valley of Jackson Hole numerous times leveling the valley floor. The present Teton landscape was established on the uplifted Teton block by alpine glaciation along deeply carved stream valleys. Several series of global cooling followed by warming over the past 2 million years resulted in the advance and retreat of alpine glaciers in the Teton

The Fountain formation created the Ancestral rocky mountains. The third oldest formation is the Lyons formation, which is approximately 270 million years. The rock found here was a sedimentary rock; sandstone. its grain size is less than 1 millimeter. Quartz, Hematite, K-feldspar and Muscovite are the minerals in rock.

Along the southern boundary were three separate arches which were rising due to the Taconic orogeny: Kankakee, Findlay, and Cincinnati. The upward movement of these arches were integral in the depressive basins forming adjacent to them: Michigan, Illinois, and Appalachian. However, the original weakening of the continental lithosphere is suggested to have been caused by the introduction of a rising diaper (Haxby, Turcotte, Bird 1976). Erosional and weathered material from the nearby forming mountains were transported and deposited into the many basins west of the mountain belt. The sediment would continue to accumulate and accentuate the subsidence which was occurring and further deepen the basin.

Ella Aerts Period 5 Your Inner Fish Discussion Answers Chapter 1 - Finding Your Inner Fish Neil and his colleagues focused on rocks from 375 million years ago because fossils from 360 million years ago were amphibians with necks and four legs. However rocks that are 380 million years old looked more like fish we know today, with fins and scale. So, it made sense that they would find the transitioning fossils in rocks that was 375 million years old.

(Harris, 2004) The downfaulting of Death Valley is correlated with the extension of the lithosphere in the Death Valley region, which plays a part to the uplifting associated with Sequoia – Kings Canyon National Park. The Batholiths of the Sierra Nevada mountain ranges are prominent in both parks, exposing “plumbing systems” in magma chambers that fed the volcanoes. “Magmatic differentiation” involves the crystallization of a magma with magma of a different chemical composition, creating more than one type of igneous rock, which can be seen in both Yosemite and Sequoia – Kings National Parks.

The Connecticut river valley was also formed from many rifts and faults that had developed. A rift valley is a region of lowland that forms where tectonic plates move apart, which is how the river valley was formed. On the other hand, the plate tectonics also formed the Appalachian mountains. The Appalachian mountains were formed by convergent boundaries, which is when two plates collide. The

Science DBQ The rock cycle is important to scientists in many ways. It shows the top three rocks and shows how they form. Geography is the study of rocks and minerals (Doc 1.) .Physical geology is the study of how rocks form into other rocks and the composition of rocks and landforms (OI), so physical geology scientists probably use the rock cycle everyday in their work.

Also during its retreat, the Laurentide Ice Sheet also left behind a desolate landscape that only contained the spores of lichen. Eventually, that lichen sprouted and attracted birds which in turn eventually brought all life back to this once ice covered land mass (PBS). Today some of the rocky outcroppings that the

Since we were given the go-ahead to choose a geological formation other than the Grand Canyon, I thought it would be interesting to learn more about Carlsbad Cavern. My family will be taking on a road trip in a couple weeks and this is one of our points-of-interest planned stops. Carlsbad Cavern is located in the Guadalupe Mountains in southeastern New Mexico. One of its most popular attractions is the Big Room, “the largest single cave chamber by volume in North America.” [1] Ironically for this assignment, actor and comedian Will Rogers referred to it as “The Grand Canyon with a roof over it.”

There are a vast amount of negative effects that are caused by the political machine in both history and today's modern society. One problem that is present throught both history and now is corruption. As shown with Boss Tweed in the 1800s and most politcs today, politicians can use the political machine for their own financial wants and needs. As an example, Boss Tweed used the political machine to create fake leases and vouchers to increase his wealth, which, as a result, financially drained New York City. Another problem is that political machines will often be negative for canidates not involved in the machines.

Second, Yellowstone doesn't have any volcanos above ground like Hawaii. The super volcano is under all the attractions. Yellowstone does get earthquakes frequently. When a earthquake hits that's high on Richter scale people fear that the super volcano could erupt, but the chances of it erupting are very low. To conclude, Yellowstone and Hawaii have geological activity, but you never know when a super volcano will

Yellowstone National Park is home to nearly 10,000 hydrothermal features (Nat'l Park Service U.S Dept. of the Interior). The hydrothermal features are caused by hydrothermal systems. These systems are dependent upon the molten rock beneath Yellowstone’s surface. Yellowstone’s thermal features are not only dependent upon molten rock but also microorganisms called thermophiles. Thermophiles depend upon the extreme heat from the magma below the surface (Nat'l Park Service U.S Dept. of the Interior).

A Storm in the Rocky Mountains, Mt. Rosalie is an oil on canvas painting currently located at the Brooklyn Museum in New York City as part of the museum’s collection of American paintings. Albert Bierstadt created this panoramic painting in 1866 in New York and its accession number at the museum is 76.79. Just as the title indicates, the painting’s subject is a storm in the Rocky Mountains, specifically at lake valley by Mt. Rosalie. Additionally, there are Native Americans riding horses by and a tepee on the bank of the valley’s river. Through the sublime use of formal elements, Bierstadt reflects the excitement and concerns with Western expansion and settlement at the time, urging caution in the U.S.’s interaction with Native Americans and

There is misunderstanding of why Arkansas is called the natural state. We have a wide range of outdoors activities. Arkansas has places where you can float the buffalo river in St. Joe, to spelunking in the caverns of Blanchard Springs, from the waterfall at Petit Jean to the carter of diamonds in Murfreesboro. Out of all of these places Pinnacle Mountain is my favorite place. Possibly because I have been unsuccessful at finding a diamond at Carter of diamonds state park.
